The existing grid pre value editors don't restore previously set values. Well, boolean, radiobuttonlist, etc. Only things like mediapicker do.

Is this by design? Or is it a bug?

It's bad for my users to have to remember what previous settings were, and re-instate them each time they want to make a change.

Umbrach 7.2.6 by the way.

I've even tried creating my own editor:

Mainfest:

{
propertyEditors: [
    {
        alias: "OnOffPicker",
        name: "On Off Picker",
        editor: {
            view: "~/App_Plugins/OnOffPicker/view.html"
        }
    }
],
javascript: [
    "~/App_Plugins/OnOffPicker/OnOffPicker.controller.js"

] }

Controller:

angular.module("umbraco").controller("OnOffPicker",
function ($scope) {
    if ($scope.model.value === null || $scope.model.value === undefined) {
        $scope.model.value = "";
    }
}

);

View:

<div ng-controller="OnOffPicker">
<input name="boolean" type="checkbox" ng-model="model.value" ng-true-value="1" ng-false-value="" />
<pre>{{model | json}}</pre>

But the same problem occurs. Is there an example of how I can code the controller to retrieve and load the previous value from the grid?
